Computer
The Sony HB-F1 was available in all black or in black and red. It was aimed at the Japanese market. It was replaced at the end of 1987 with the Sony HB-F1II to better compete against the Panasonic FS-A1.
The computer comes with an external power adapter, it includes a pause button that allows users to pause the system at will and a speed slider which can be used to slow down the system.

Firmware
The firmware is launched automatically when you boot the machine. Bypassing this software on startup requires the user to press the DEL key during boot until a Beep sound.
From MSX-BASIC, you can go to the Personal Databank with CALL HITBIT or _HITBIT.
Trivia
When keeping the Y and P keys pressed during boot, you will get a scrolling list of the development team followed by a digitized voice saying "It's a Sony!". A video of it is available here. The Y and P keys seem to refer to "Yellow Panther", which is also encoded as a message at the beginning of the ROM. The message (written backwards in the ROM) reads "A Yellow Panther Production, 1986".
